Hi Ravikumar,
A qualified table is a special kind of lookup table. It can be used to efficiently store complex relationships between a main table record and one or more lookup table records that contain various types of additional information.

A qualified table stores a set of lookup records, and also supports qualifiers, database u201Csubfieldsu201D that apply not to the qualified table record by itself, but rather to each association of a qualified table record with a main table record.
Qualified lookup tables are used to store the values of Two types of fields Qualifiers and non Qualifiers.
Qualifiers are the fields whoes values changes based on the values of other fields called Non Qualifiers.And are associated with the main Table Records.
Non Qualifiers are only part of Qualified lookup Tables.
In Data Manager QualifiedLookUp Tables appear in the lower right Part.
For example in your main table supoose you have an Employee Repository that maintains employee information (Name,Telephone,Address etc).One employee can have sitting arrangement on different office locations.
Then if Location is your main table field in that case for 10 places you have to make 10 seperate entries of One Employee name with different locations,that will unnecessarily increase the records of your main table and also duplicate for Employee name field as well.
To resolve this make a look up field location in main table for qualified lookUp Table Locations.
In Locations table create a Non Qualifier field OfficeADD(lookup flat )for Officelocation table .
And create two more fields DeskNo. and Telephone No.(both as qualifiers)for every location the desk no. and telephone no. will be different.
In Officelocation table has one field Name which contains address of diffrent locations.
Now according to the Qualifier and Non Qualifier concept
In main table for an Employee say Ravindra you can go qualifiedLookUp table and select a value for OfficeADD(a non qualifier) and set valus for Desk no. and telephone no.(Qualifiers) as well.
